Signal recording apparatus and method
First Claim
1. An improved signal recording apparatus of the type in which a plurality of fields of video signals are sequentially recorded on a corresponding plurality of concentrically arranged tracks on a rotary recording medium, and selected ones of the remaining tracks on the recording medium are arranged to have audio signal segments recorded thereon, some of which are intended to be reproduced sequentially, wherein the improvements in the recording apparatus comprise:
- (a) means for time-compressing the audio signal segments;
(b) means for generating control code data for controlling a reproduction sequence of audio signal segments recorded in said plurality of recording tracks;
said control code data including address data indicating a track number and address on said rotary recording medium, data for discriminating whether a track being reproduced is one of the tracks having an audio signal segment which is intended to be reproduced in a sequence with other recorded audio signal segments, and data indicating a track number of a video signal segment corresponding to the audio signal segment being reproduced;
(c) table memory means for storing said control code data including said address data, said discriminating data and said track number data;
(d) means for recording said control code data in predetermined portions of said respective audio tracks together with said time compressed audio data; and
(e) means for recording said control code data stored in said table memory means on a control track at a predetermined location on said rotary recording medium.

Abstract
Described is a method and a recording apparatus whereby audio and video signals can be recorded on a plurality of recording tracks on the same recording medium. A series of temporarily consecutive audio signals can be recorded across a plurality of tracks. On at least the audio track, information signals including the leading track number, the next following track number and the number of the video track bearing the corresponding video signals, are recorded. The track number data of the information signals on these audio tracks are written in corresponding positions of a digital, table memory. These control code data are recorded on a predetermined control track on the recording medium such that a series of desired audio signals and the corresponding video signals can be selectively reproduced smoothly and promptly by first reading the control track and then reproducing the audio and video tracks in accordance with the control code data information.
